Abstract

A molding method of and an apparatus for making a resin molded article by using a mold apparatus (23,24) includes the steps of: a) starting filling resin into a cavity (37) forming part of the mold apparatus (23,24) before a mold closing process is finished; b) finishing the mold closing process after filling the resin into the cavity (37) forming part of the mold apparatus (23,24) is finished; and c) implementing a mold clamping process after the mold closing process is finished. A further claim is directed to the manufactured product.
